3-fold is one of the best choice for hotels,the firt is extra narrow depth,the second is very comfort sleeping (No bar feelings) and the third is the extra comfort seat feeling (strong foam support when the foam mattress is folded three times).But the wrong operation problem is a big issue for hotel use.

Now Linkrest designed an optional part to lock the wrong steps.You have to follow the correct steps to unclock the bracket for sleeper protections.

Also we adapt square tube design for long cycle life and strong loading capacity for end bar in case some people sit on the end bar in open position.
